Improvement in lanterns



UNITED STATES PATENT ANDREW J. WARREN, OF NEW YORK, N. Y.

IMPROVEMENT IN LANTERNS.

Specification forming part of Letters Patent No.146,415, dated January 13, 1874 #application filed tins To all whomct may concern:

Be it known that I, ANDREW J. WARREN, of New York, county of New York and State of New York, have invented certain new and cap or top of the lantern, whereby a draft' is obtained around all sides and top of the cap, the object being to enable the consumer to use the cheaper forms of carbon-oil, Where heretofore the more expensive lard and sperm oils have been required, and also to protect the l hand oi' the carrier from heat.

In order to enable others skilled in the art to which my invention appertains to make anduse the same, I will now proceed to describe its construction and operation, referring to the annexed drawing, in Which- Figure l is a plan view of a lantern with my invention attached. Fig. 2 is a sectional view of the cap.

A represents a lantern constructed in any of the known and usual ways. B represents the cap of the lantern provided with a central oriiice, a. C represents a square frame or cup attached permanently to the top of the cap B and surrounding the orilice a. Each side of the frame or cup C is provided with avertical slot, b, in the center from the lower edge upward for a suitable distance. The frame or cup C is surrounded by an exterior frame formed of two plates, D and D', the plate D being bent to form a top for the interior frame C a suitable distance above it, a-nd the ends of the plate passing vertically downward parallel with and a short distance outside of the two opposite sides of the frame C. The plate D' is bent in the same manner parallel with and a short distance beyond the .other two sides of the interior frame C; but the middle December 24, i873.

portion of this plateD' is corrugated, as shown and elevated above the middle port-ion of the plate D. The plates D and D being of about the same width vas the sides of the interior frame C, suitable openings are left at the cor ners.

By this construction of the cap of the 1an-` tern, sufficient draft is obtained to allow of the use of kerosene-oil or any of the cheaper forms cool, and thus protecting the hand of the carrier from the heat.

A lantern provided with a cap of this constructionwill prove a cheap, and at the same time good and durable, signal-lanternfor use on railroads.

Having thus fully described my invention,

what I claim as new, and desire tosecure by Letters Patent, is-

The combination, with the cap B of a lantern, of the interiorirame C, having a central vertical slot, b, in each side, and the exterior frame composed of the plates D and D', the latter being corrugated in the center, all constructed and arranged substantially as and for the purposes herein set forth.

In testimony* that I claim the foregoing as my invention, I hereunto affix my signature this 24th day of December, 1873. y

ANDREW J. WARREN.
